Incremental Changes in Qrs Duration as Predictor for Incident Cardiovascular Disease: a Prospective Follow-up of a Randomly Selected General Population Sample During a Decade Beyond
Abstract:Background: The QRS complex has been shown to be a prognostic marker in coronary artery disease. However, the changes in QRS duration over time, and its predictive value for cardiovascular disease in the general population is poorly studied.Hypothesis: Increased QRS duration from the age of 50 to 60 is associated with increased risk of major cardiovascular events during a further follow-up to age 71. Method: A random population sample of 798 men born in 1943 were examined in 1993 at 50 years of age, and re-exa… Show more
